Killing矢量场时空上量子场论的形变

Deformations of quantum field theories on spacetimes with Killing vector fields

Claudio Dappiaggi, Gandalf Lechner, Eric Morfa-Morales

摘要:

最近构造和分析的变形量子场论的翘曲卷积被推广到一类弯曲时空。这些时空携带着一族楔形区域,它们与闵可夫斯基空间中林德勒楔形的庞加莱变换具有基本的因果性质。在变形量子场论的背景下,它们扮演着量子场和观测量的典型局域化区域的角色。作为这一过程的一个具体例子,研究了自由狄拉克场的形变。

英文摘要:

The recent construction and analysis of deformations of quantum field theories by warped convolutions is extended to a class of curved spacetimes. These spacetimes carry a family of wedge-like regions which share the essential causal properties of the Poincare transforms of the Rindler wedge in Minkowski space. In the setting of deformed quantum field theories, they play the role of typical localization regions of quantum fields and observables. As a concrete example of such a procedure, the deformation of the free Dirac field is studied.
